Aqara Curtain Driver E1

I have a couple of these and can answer a few of the questions on this thread:

  1. Yes when these are setup and configured without the aquara hub manual control works fine (you tug on the curtain and they open / close)
  2. you can set the direction of the curtain in the zigbee2mqtt settings:

I am really struggling to get them setup correctly though. The travel calibration without the aqara hub really seems to not work properly. I have either got into a state where the driver stops about 1" short leaving a 2" gap in the middle of my curtain pair when they are closed or there is no calibration and each driver runs for around 30 seconds after it has reached either end of the pole just spinning the wheel on the bar.

I also have issue with the wheel slipping on the bar…
